I don't have any good suggestions for testing cache stuff in general,
but this one is pretty easy to test if you have the board in question.
Because U-Boot is loaded *as if it were linux* by the manufacturer's
bootloader, the initial location of U-Boot is the same as where we
ultimately load the Linux kernel. Without this patch the symptom is
the failure of Linux to start from U-Boot.
